To all 'LU/wm it ,may concern.'

Be it known that JOSEPH H. AMES, residing` at New York, county of NewYork, State of New vYork, and being a citizen of the United States, haveinvented certain new and useful improvement-s in an Erection Truck, ofwhichthe following is a full, clear, and exact description, suchv aswill enable others skilled in the art to which it appertains to make andto use the same, reference being had to the accompanying drawings, which`illustrate the preferred form ofthe invention, though it is to beunderstood that the invention is not limited tothe exact detailsofconstruction shown and described, asit is obvious that variousmodications thereof within the scope of theclaims will occur to personsskilled in vthe art.

v In said drawings:

Fig.- 1 is a view in elevation, showing the manner of using my improvederection truc-k;

Fig. 2 is a plan view of my device, parts being broken awayto show otherparts more clearly;

Fig. 3 is a section taken on the line 3-3 of Fig. 2;

Fig. .4 is a central vertical section showing y the driving dog whichengages the conveyor chain in operative or engaging position;

F 5 is a fragmentary section showing the dog in theinoperative orrelease position;

Fig. 6 is a section vtaken on the linev 6-6 of Fig. l; and

Fig. 7 is asection taken on the line 7 7 ofFig. 2 showing the manner ofsupporting ra seat from the truck bolster.

It is an object of my invention to provide an improved truckuponwhichrailway carbodies may be supported during-*erection. .Itlis also Vanobject ofmy invention to provide a truck of the typedescribed dcsignedto vbe moved forward continuously a chain conveyor or other suitabledriv- `ing means during: the construction of the car l body supportedthereon. :It is alsoan vobject of my invention to provide a truck of`the type described that 4may .be readily :adapted to support :bodies of.different widths. It is .also -an .object of my invention Vtor provide.a means for quickly engag- -ing ythe truck with or 'disengaging it fromthe driving means.

With these and other objects xin view, my `improved truck comprises y.aplurality of cast side? frame members 1, of substantially beam shape atthe center and having bifurcated ends formed of `channel- -shaoed endsections 2 and seats 3 formed integral withfthe center portion of theside frame to accommodate a reduced endportion 4; formed on a castbolster member The bolster is of substantially,-beam shape and issecured to theside 'frames by the rivets 6. In bearings '7 formed in theend sections 2 there are mounted axles ,8 which are secured in place bycotter pins 9 and have wheels 10 .journaled thereon. The outer ends ofthe en'd sections 2 at each end of each side member `1 are vjoined bychannel-shaped lend members 1l secured to flanges 12 formed on the en'dsections/2. To the bottom flanges of the end members 11 at the vfrontofthe truck there `are secured brushes 13 which serve @to remove small yobstructions from the `rails -14 on which the wheels 10 travel.l -lVheelcovers 15 are secured to the end sections 2 andthe upper flanges of theend members 11'and prevent small objects from falling intovthe wheelopenings.

rlhe bolster 5 is provided at its center, adjacent to its upper flange,witha bearing 16 to receive a pin 17 which secures cast center lpedestal18 to its seat on thenpper flange of the bolster 5. The vupper `end ofthe pedestal 18 is formed with a flat face having a central .circularopening adapted to j receive the cylindrical shank 19 formed on thecenter plate 20. The center plate 2O is shaped to conform to theworvkiit is int-ended to support and is detachably and rotatably held inthe opening inthe ped estal r1S by pin 21 which engages inkcooperatinggrooves `formed inthe shank 19 and in Vthe wall of theopening in the pedestal.

Adjacent each end of the bolsterl 5 zu side pedestal 22 is secured toits seat on the upper :flange of the bolster by a pin 23 which has abearing, not showinin the bolster similar to the bearing 16. Eachpedestal 22 is provided at its top with an opening to receive the shank24-of a side the walls ofthe opening'in the pedestal.

The side bearings Q5 are mounted eccentrically upon their shanks 2i asillustrated in 'full lines in 3, and adapted to be turned laterally tothe position indicated in dotted lines in Fig. 3, it' it is desired toextend the supporting areay ot' the bearings to provide a wider support'for the work carried by them. Bearings of different heights areprovided and are substituted when necessari.v to properly supporty thework.

On the forward side et the web otl the bolster 5 there is mounted abracket 2T tor supporting a collapsible driving mechanisn'i. The bracketis provided Tith a pair ot projecting arms in which is mounted a pin 28having a driving dog or puller pivotally mounted thereon. The dog Q9 islong enough to project into slot formed in the floor and engage with thelinks of a chain conveyor 30 that is driven by any suitable means and ata. suitable speed. The dog 23 has -formed integral therewith a hook 3ladapted to be engaged by a latch secured to bolster 5 by eye-bolts 33,when the dog 29 is raised to the release position as shown in Fig. 5.Mounted in the dog 2t) is a pin 3st upon which an operating, handle 35is pivotally mounted7 the handle 35 being kept from engagement with thetloor by a support 3G Secured to theV lower flange ot the bolster :'i.There is also pivotallyv mounted on the pin 3i. a yoke 3.7 having a ilatstrap-like portion 3S adapted to project through an opening 3f) in theweb ot the bolster 5 and to rest upon the bottom flange ot the bolsterwhen the dog 29 is in position to engage the chain 30. The strap-likeportion 38 is provided with a tapered projection 40 adapted to engagewith the bottom tlange of the bol ster 5, the outer edge ot the bolster'llange having a portion provided with an inclined surface to engage withthe inclined sin-face of the projection 40. Yoke 3T is held in operativeengagement with the lower llange ot the bolster by a locking cam allmoving between the arms d3 ot bracket secured to the web ot bolster Thelocking cam is lixed to a transverse shaft 4Q having a bearing in thearms d3 olf bracket lf3 and also journaled in bearings on the side tramemembers l. The sha't't is fitted at its ends with operating handles -iwhich are limited in their movement by means ot' the stop lugs 46 on theside trames.

For some ot the operations in the construction ot car bodies it isdesirable to have the workman travel with the truck so there is provideda seat support ti' upon which a. seat 48 is adjustably mounted. llhesupport ll' is provided with oppositely disposed projections lf) and alltormed ot' pairs ot metal strips secured together and to the support TJTand having' their outer ends bent in opposite directions to torni teetadapted to engage with the web and bottom tlange,

respectively. ot the bolster As .shown in i and '7, the end ot thesupport t7 passed through an opening in the bolster web so that theprojection El engages with one side ot the bolster web and theprojection en'V 'es with the bottom i'lange on the other side oit theweb.

In the construction of' car bodiesl using my erection truck pair ol thetrucks are placed on the erection track. spaced the proper distance torthe reception ot the trame members and the i une members. restedthereon. The leading' truck has, itsA dog 3) placed in position toengage the coin.'e},'or chain 20 while on the other truck the dog QS) isheld clear ot the chain fill by the latch 3Q, the second truck beingpulled b v the trame me1nbers carried thereon. "lo place. the dog Q inthe engaging position. the latch 3Q is dis engaged trom the doe' :25) sothat the dog Q9 wll take the posib on shown in Fie. l

vith the yoke 2 i? projecting through t-he opening 3f) and t ieprojection l0 in engagement with the bolster bottom flange. The lockingcani is then brought into engageient with the yoke 23T b v the operationot the shaft l2 by the han-lle l5 so that thel yoke 3T and projectionlll are locked in engeinent with said bok-iter llauge. lt

be noted that the pull evertedibv the dog Q9 on the yoke, 23T tends tooperate the locking cam l to 'torce the voke 3T against, the bolsterflange. To diseugage the dog QQ Yfrom the chain ltl. the cam 1li is dis-'eel from the yoke 3T and the dogy 2f) y means ot handle 5K5 until thelatch ges with the hook 8l. as shown in .lt will be noted Ytrom theVforegoing that when two trucks built as described are positioned inspaced relation upon a straight track they provide complemental elementsot' a mobile crectioi'i bench having a variable supporting area tor theaceomimnlation ot work ot dill'erent length and width. lt will also henoted that low side trames ol the individual trucks and the relativelyhigh work-supportiup` pcdestals and the. use ot .s pro\.'ide ample room'or the operations ot the workmen at the truck positions.

lVhat I claim is:
